The Neoplasm trait in pea pods is reported to be due to the lack of ultraviolet (UV) light in glasshouse conditions or in response to pea weevil (Bruchus pisorum L.) damage. This pod deformation arises from the growth of non-meristematic tissue on pods of domesticated peas (Pisum sativum L. subsp. sativum). Neither expressivity, nor the effect of pea weevil on neoplasm in the tall wild pea (P. sativum L. subsp. elatius (M. Bieb.) Asch. & Graebn.), have been adequately studied. We aimed to study the expression and inheritance of neoplasm in the tall wild pea and crosses between domesticated and tall wild peas grown in the glasshouse (without pea weevils) and in the field (with pea weevils) under natural infestation conditions. Neoplasm was found in all pods in tall wild peas when grown in the glasshouse, while it was not detected on pods of field-grown plants despite heavy pea weevil damage. In inter-subspecific crosses between P. sativum subsp. sativum and P. sativum subsp. elatius, all F₁ plants had neoplastic pods, and the F₂ populations segregated in a good fit ratio of 3 (neoplasm): 1 (free from neoplasm) under glasshouse conditions, which suggests that neoplasm on pods of the tall wild pea was controlled by a single dominant gene. Expressivity of neoplasm in the progeny differed from parent to parent used in inter-subspecific crosses. There was no relationship between neoplasm and damage by pea weevil under heavy insect epidemics under field conditions. The neoplasm occurring under glasshouse conditions may be due to one or to a combination of environmental factors. Since wild peas are useful genetic resources for breeding programs aiming at fresh pea production that could be utilized under glasshouse conditions, negative selection could be considered in segregating populations.

豌豆（Pisum sativum subsp。sativum）和高大豌豆（Pisum sativum subsp。elatius）杂交后代性状的遗传和表达

据报道，豌豆荚中的新生物性状是由于在温室条件下缺乏紫外线（UV）或对豌豆象鼻虫（Bruchus pisorum L.）的损害所致。这种荚果的变形是由于豌豆（Pisum sativum L. subsp。sativum）荚果上的非变生组织的生长而引起的。豌豆象鼻虫对高大野生豌豆（P. sativum L. subati。elatius（M. Bieb。）阿施。＆Graebn。），已经进行了充分的研究。我们的目的是研究在自然侵染条件下在温室（无豌豆象鼻）和田间（有豌豆象鼻）中生长的高野豌豆以及家养和高野豌豆之间的杂交瘤的表达和遗传。在温室中生长时，在高大的野生豌豆的所有豆荚中都发现了肿瘤，尽管豌豆象鼻虫受到了严重破坏，在田间种植的植物的豆荚中也未发现。在P. sativum亚种之间的亚种间杂交中。茄子和茄子亚种。鼠尾草，所有F ₁植株都有瘤荚，F ₂在温室条件下，这些种群以3（neoplasm）：1（不含赘生物）的合适比例分离，这表明高大豌豆荚中的赘生物由单个显性基因控制。在子间种间杂交中，后代中肿瘤的表达能力因亲本而异。在野外条件下，昆虫与豌豆象鼻虫在重度昆虫流行中的损害之间没有关系。在温室条件下发生的肿瘤可能是由于一种或多种环境因素引起的。由于野生豌豆是育种计划的有用遗传资源，可用于在温室条件下利用的新鲜豌豆生产，因此在隔离种群时可考虑采用负选择。
